FRQ prompt

Free Response Question:
A 4 kg block slides down a frictionless inclined plane that is 5 m long and makes a 30° angle with the horizontal. (g = 10 m/s²)

(a) Calculate the acceleration of the block along the incline.
(b) Calculate the velocity of the block at the bottom of the incline, starting from rest.
(c) If the incline were not frictionless and the coefficient of kinetic friction were 0.2, calculate the new acceleration of the block.
